**Math 260 DeVry Week 3 Quiz**

**Question 1. Question : (TCO 2)** Find all of the derivatives:

y = -3×3 + 2×2 – 9x + 2?x + 13 -9x^2+4x-9+2pi -18x+4 -18 0

Instructor Explanation: See Chapter 23.9, Week 2 Lecture

y’ = -9×2 + 4x – 9 + 2?, y” = -18x + 4, y”’ = -18, y(4) = 0

**Question 2. Question : (TCO 2)** Choose the letter of the correct Chain Rule for

f(x), g(x), h(x)

are continuous functions of x.

**Question 3. Question : (TCO 2)** Find y’ for y = (x2 – 3)(2×2 – 1),

use the product rule and simplify your answer.

**Question 4. Question : (TCO 2)** Find f ‘(-2) for

**Question 5. Question : (TCO 2)** Find v(t) and a(t) for s(t) = 2(3t2 + 1)2, then find the velocity and acceleration at 1 second.

**Question 6. Question : (TCO 2)** Find the expression for the slope of the tangent line for .

Then find the slope of the tangent line at x = 1.

What is the slope of the curve, f(x),

at x = 1?
